refactor: fix code review findings across all scripts

Critical: stream large file downloads (OOM fix), fix basename match
in auto_fetch, include hashes in pack grouping fingerprint, handle
not_in_zip status in verify, fix escaped quotes in batocera parser.

Important: deduplicate shared group includes, catch coreinfo network
errors, fix NODEDUP path component match, fix CI word splitting on
spaces, replace bare except Exception in 3 files.

Minor: argparse in list_platforms, specific exceptions in download.py.
